UNITED STATES FREDERICK In KENNEDY. OF CLEVELAND, OHIO- MOISTURE AND VERHIN' PROOF MATERIAL.

Application filed December 9, 1921. Serial Io. 521,185.

To all whom it may concern):

Be it known that I, FREDERICK L. KEN- my, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Moisture and Vermin Proof Materials, of which the following is a full, clear, and exact description.

The resent invention relates to material which 18 so prepared as to be resistant to moisture, and also to be resistant to attack of vermin or insects, because of the qualities enumerated.

The material may be conveniently used for repairing or the making of containers in which may be contained articles which it is desired to protect from moisture and from vermin or insects.

Reference should be had to the accompanying drawing forming a part of this s ecification, in which the figure is a sectional elevation showing in exaggeration the sectional parts of the material.

The material forming the subject matter a of the present a plication is made up of three elements. he first element which forms the base or body or carrier is indicated atl, and this material may be of any suitable substance, such as paper or cloth. The body 1 has applied to one side, thereof a layer of wax or parafiine or any other suitable moisture resistant substance. This material may be placed on the sheet or body 1 in any suitable manner, various methods being very well known in the art at the present time.

On the opposite surface of the body or sheet 1 there is applied a layer of suitable 40 vermin or insect repellent or destroying substance, and as a very good example of that I may mention naphthaline, for naphthaline may be readily'put in condition so that it may be coated upon the surface of the body or sheet 1 by machinery and methods similar to those employed for applying wax coatings which is very well known in the art.

In view of the fact that a coating of parafln will not adhere toa sheet of paper impregnated with naphthaline and a coating of Melted naphthaline is placed in t e lower 'passageof the coating material through the .pmg material for the wrapping of such 0 naphthaline will not adhere to a sheet of paper impregnated with araflin, the first coating must be so applie to the sheet that the material of the coating extends only partially through the sheet. To accomplish this I employ a well known coating machine. which has superposed tanks for coating material in which are located coating rolls which act upon .opposite surfaces of the sheet. The sheet in passing through the machine runs over the coating roll in the lower tank around a. chilling and reversing roll and over the coating roll of the up r tank.

tank and melted parafiin in the upper tank, the naphthaline being applied to one side of the sheet and the paraflin to the other. In the operation of the machine the rolls are run at a high rate of speed to pass the sheets rapidly over the rolls so that the sheet passes from the coating roll to the chilling roll with sufiicient rapidity to prevent the sheet.

When a sheet of material is completed em bodying the present invention it will, therefore, contain a body portion with the opposite surfaces prepared and coated the one with a moisture repellent substance, and the other with averminor insect destroying substance.

This material is capable of being packa ed in rolls and maybe used either as wra jects as it is desired to protect from moisture or from insects or vermin, or the ma. terial may be made into containers in which the object to be protected may be laced.

Having described my invention, claim .1. Material of the character described having a body portion of flexible sheet form which sheet is coated on one side with moisture repellent material and on the other side is coated with naphthaline.

2. Material of the character described comprising a body in sheet form one side of which is coated with arafiine and on the other side is coated W151 naphthaline.

In testimony whereof, I hereunto afiix my 100 signature. FREDERICK L. KENNEDY.
